Patent EP-0916847-A1 (EP)
Inventor: BEARINT DAVID E
IPC: F04C27/00
Filed: 1998-09-30
Abstract: A variable capacity, vane-type compressor has a cylinder block (13) with an
oval rotor chamber (15). A plurality of vanes (17) mounted in slots on a rotor (19) rotate
inside the rotor chamber on a shaft (21) that is concentric with the minor diameter
of the rotor chamber. Valves discharge refrigerant gas from the rotor
chamber. The front nose block (31) is located on the front side of the cylinder
block and contains a bore (33) for the rotor shaft and a set of needle roller
bearings (35) which supports the forward end of the shaft. A circular O-ring
groove (37) with an O-ring is located on the rearward side of the front nose block
at its perimeter for sealing between the front nose block and the forward side
of the cylinder block. The cylinder block has internal, weight-reducing voids
located outboard of the rotor chamber. The lower voids serve as an oil sump (16)
and supply high pressure lubricant to the undervane pressurization manifolds.
Like the front nose block groove, the cylinder block has a circular groove (45)
machined on a rearward side. The cylinder block groove contains an O-ring
for sealing against the rear side block. The rear side block (51) has a bore (53) for the
shaft and a needle roller bearing (55) which supports the rearward end of the
shaft. A circular O-ring groove (57) is machined on the rearward side of the rear
side block and holds an O-ring for sealing between the rear side block and the
rear head. A lubricant transmitting passage (67) is located in the blocks. The 
passage leads from the intake chamber (63) at the rear of the compressor to the
bore at the front radial bearing. Each of the components has bolt ears with
threaded bolts (75) for securing the components together. The bolt ears are
located in the formerly wasted space at the four corners providing the
compressor with a rectangular external configuration.

Abstract: The quantum cascade (QC) photon source according to this invention can emit
simultaneously at two distinct wavelengths, typically both in the mid-infrared. This is
accomplished through provision of a semiconductor layer structure in which, at the proper
bias voltage, electrons are injected into a energy level E 3  and then forced to cascade
through an intermediate level E 2  before reaching the ground state E 1  of the active region.
In the process, photons of energy E 3 -E 2  (wavelength λ 1 ) and E 2 -E 1  (wavelength λ 2 ) are
emitted. Dual wavelength photon sources according to this invention can be used in a
variety of ways, e.g., to determine the absorption of a gaseous sample at wavelengths λ 1 
and λ 2 , exemplarily to determine the concentration of a particular chemical compound in
the sample.

Abstract: A system controls the pressure at which conditioned is to be provided to one or more
zones to be heated or cooled by the conditioned air. The system actively computes a
setpoint for the pressure with a location in a duct system upstream of where any of the
conditioned air is to be provided to the zones. The setpoint is computed as a function
of the positional statuses of dampers within the duct system that regulate the flow of
the conditioned air to the respective zones. The actively computed setpoint is
compared with a sensed pressure in the duct system in order to determine whether the
pressure in the duct system needs to be changed.

Abstract: The present invention concerns a method of controlling errors in packets
transmitted over at least one transmission link between a transmitter and a receiver,
said transmitter receiving from an input multiplex packets belonging to a plurality of
virtual circuits and transmitting them in the form of sequences of packets over a or said
transmission line, said receiver, on reception of a packet, checking whether it is in the
order of the sequence or out of life time and if so, delivering it to an output multiplex,
and if not, sending to the said transmitter a negative acknowledgement of the packet or
packets which have been lost in order to have it or them retransmitted. 
     According the invention, at the transmitter side, two index are allocated to each
packet to be transmitted over the transmission line, one index indicating the sequence
number of the packet to be transmitted and the other index has a value amongst at least
two specific values, one value meaning that no resequencing is needed and the other
(or the others) respectively meaning that the difference between the sequence number
of the packet to be transmitted and the previous packet of the same virtual circuit is
larger than a predetermined value (or predetermined values), and, at the receiver side,
on receipt of a packet corresponding to the one expected, a pointed packet is
determined which sequence number is given by the difference between the sequence
number of said received packet and the predetermined value representated by the
second index carried by said received packet, and if said pointed packet and all packets
sent by the transmitter before have already been correctly received by the receiver and
delivered to the output multiplex or have been discarded by the life time, said received
packet is delivered to the output multiplex, and if it is not the case, said received packet
will be retained until the pointed packet and all the packets before will be delivered or
discarded by the life time.

Inventor: GIANGRECO CHRISTIAN
IPC: G10K11/178
Filed: 1998-12-15
Abstract: The system uses a local noise detector producing a reference signal for elimination from detected acoustic signals. The system for detecting acoustic signals in the presence of noise includes use of a vibration sensor (71) placed directly next to at least one source of parasitic noise (11). A signal is derived from this and used as a reference signal. A further signal is derived from an aerial (2) measuring acoustic pressure signals and this is correlated with the reference signal and fed to a processing unit (10). The support for the aerial comprises a dynamic system (4,5,8) which controls movement of the support, with an error detector (6) solidly attached to the aerial to determine a minimum signal condition. With the benefit of the dynamic support for the aerial, and the reference signal provided by the detector (71), the characteristics of an unknown external acoustic source may be determined.

Abstract: An add/drop filter (10) for optical wave energy incorporates a Bragg grating (27) in a very narrow waist region (12) defined by merged lengths of elongated optical fibers (30, 31, 34, 35). Light is propagated into the waist region via adiabatically tapered fibers (20, 21, 24, 25) and is tranformed from two longitudinally adjacent fibers into two orthogonal modes within the air-glass waveguide of the waist and reflected off the grating from one fiber into the other. The geometry of the waist region (12) is such that the reflected drop wavelength is polarization independent, without lossy peaks in the wavelength band of interest. Back reflections are shifted out of the wavelength band of interest. High strength gratings are written by photosensitizing the waist region fibers. Narrow spectral bandwidth gratings are apodized by both a.c. and d.c. variations in writing beams. A coupler device employing these is precisely arranged in a support structure which provides temperature compensation.
